Aiming at the complexity and localization for common methods of slope stability evaluation
this paper combines fuzzy mathematics theory with AHP and establishes a comprehensive model of slope stability evaluation. Meanwhile
the paper uses this evaluation model to analyze the stability of high slope of Geheyan PowerStation . The result indicates that the model makes slope stability evaluation more comprehensive
more scientific and clearer to the truth. It is feasible and its result is reliable. It provides scientific basis for project decision-making .
